Batching :

Browse Source 
- BatchNode can now batch a scene graph with several materials. It creates a batch by material
- Added a SimpleBatchNode that batch only geometries (no sub node graph) for better performances
- removed RF_REFRESHBATCH from Spatial as it's no longer needed
- changed test cases a bit

* usage is like any other node except you have to call the {@link #batch()} method once all geoms have been attached to the sub scene graph and theire material set
* (see todo more automagic for further enhancements)
* all the geometry that have been batched are set to {@link CullHint#Always} to not render them.
* the sub geometries can be transformed as usual their transforms are used to update the mesh of the geometryBatch.
* sub geoms can be removed but it may be slower than the normal spatial removing
* Sub geoms can be added after the batch() method has been called but won't be batched and will be rendered as normal geometries.
* To integrated them in the batch you have to call the batch() method again on the batchNode.
* To integrate them in the batch you have to call the batch() method again on the batchNode.

* TODO account for sub-BatchNodes
* TODO account for geometries that have different materials
* TODO normal or tangents or both looks a bit weird
* TODO more automagic (batch when needed in the updateLigicalState)
